After receiving a ten minute back rub, participants had their oxygen consumption and cardiac output measured. Results showed that relaxation was caused by central and peripheral components of oxygen consumption being altered and a decrease in cardiac output.

Results of this study showed that massage-like stroking of the abdomen decreased the blood pressure of anesthetized rats. Massage of the ventral and lateral sides of the abdomen caused arterial blood pressure to drop.

People who had been diagnosed with hypertension were given massages for five weeks (ten 30-minute sessions) experienced lowered blood pressure, less hostile behavior, less depression and lower salivary and urinary hormone levels (cortisol). Researchers concluded that massage therapy may be useful in lessening the symptoms of hypertension and lowering diastolic blood pressure.
